22		*  NOTES:
23		*    The Ctrl key works like a qualifier for special actions:
24	<	*      Ctrl-Tab = suspend DGA mode
24	>	*      Ctrl-Tab = suspend DGA mode (TODO)
25		*      Ctrl-Esc = emergency quit
26		*      Ctrl-F1 = mount floppy
27		*      Ctrl-F5 = grab mouse (in windowed mode)
28		*
29		*  FIXMEs and TODOs:
30	+	*  - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux
31		*  - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)
32		*  - Mouse acceleration, there is no API in SDL yet for that
33		*  - Force relative mode in Grab mode even if SDL provides absolute coordinates?
#	Line 35 | Line 36
36		*  - Events processing is bound to the general emulation thread as SDL requires
37		*    to PumpEvents() within the same thread as the one that called SetVideoMode().
38		*    Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
39	+	*  - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
40	+	*  - Backport hw cursor acceleration to Basilisk II?
41	+	*  - Factor out code
